10 Best Propane Quiet Portable Generators 2025 in the United States

The Westinghouse 11000 Peak Watt Dual Fuel Portable Inverter Generator stands out with its impressive power output, delivering 9000 running watts and 11000 peak watts on gasoline, and slightly less on propane. This makes it highly capable for residential use, particularly for those in need of reliable backup power. The remote electric start feature with a key fob adds convenience, especially during adverse weather conditions, while the push button and recoil start provide additional starting options.

Fuel efficiency is commendable with a 9.8-gallon tank offering up to 17 hours of runtime. This, coupled with its dual-fuel capability, provides flexibility and longer operation times. However, its weight at 187.4 pounds might affect portability, which could be a drawback for some users seeking a more mobile solution.

Safety features are robust, including a CO sensor and automatic low oil shutdown, ensuring safe operation. The generator is equipped with standard outlets, including transfer switch ready ones, all protected with rubber covers, enhancing safety further. The low Total Harmonic Distortion (THD) makes it safe for sensitive electronics, a major plus for households relying on electronic devices.

Despite its strong performance and features, the size and weight make it less ideal for those who prioritize easy transportation. It's suitable for those who can accommodate its bulkiness or plan to keep it stationary. The generator meets EPA compliance and comes with a 3-year limited warranty, backed by a solid customer service network, providing peace of mind regarding reliability and support.

The Westinghouse 5000 Peak Watt Super Quiet Dual Fuel Portable Inverter Generator is designed to meet the needs of those seeking a balance between power and quiet operation. With a starting wattage of 5000 and a running wattage of 3900, it offers ample power to run essential appliances, making it suitable for travel trailers and home use. Its dual-fuel capability allows for flexibility, running on either gasoline or propane, which can be handy in various situations.

One of its standout features is its quiet operation, producing only 52 decibels of noise, comparable to a normal conversation, which is ideal for camping or residential use. The generator is also highly fuel-efficient, with a runtime of up to 18 hours on a 3.4-gallon gas tank, and it includes an 'Economy Mode' to maximize efficiency further.

Portability is enhanced by its telescoping handle, although its weight of approximately 124.7 pounds might make it a bit challenging for solo transport. The remote electric start feature adds convenience, allowing for easy operation without manual effort. Safety features include automatic low oil and carbon monoxide (CO) shutdowns, which are crucial for preventing potential safety hazards. It also includes multiple outlets, including standard household, RV, and USB ports, providing versatility for various electronic connections.

Despite these strengths, its weight could be a drawback for some users looking for something more lightweight. Additionally, while it offers parallel capabilities, it might require additional equipment to connect with other units for more power. These factors should be considered depending on individual needs and circumstances.

The WEN 3800-Watt Inverter Generator is a strong contender in the propane-quiet-portable-generator category. With a starting wattage of 3800 watts and a running wattage of 3400 watts, it provides solid power output, making it suitable for various uses including camping and RVing. One of its standout features is its super quiet operation, which minimizes noise, making it a good fit for environments where noise pollution is a concern. The fuel efficiency is also notable, offering up to 8.5 hours of runtime at half load on its 2.2-gallon tank, which is reasonably fuel-efficient for its size and power output.

Portability is another selling point; although it weighs 99.2 pounds, it is designed to be moved around with ease, which is beneficial for outdoor activities. The electric start mechanism adds convenience, ensuring that the generator is easy to start without much hassle. Safety features such as the fuel shutoff, which uses up the remaining fuel in the carburetor before shutting down, help to extend the generator’s lifespan. Additionally, it produces clean power, which is important for preventing damage to sensitive electronics like smartphones, tablets, and laptops.

However, at nearly 100 pounds, it might be on the heavier side for some users to transport frequently. Also, while it is gas-powered, it does not use propane, which might be a downside for those specifically looking for propane generators. The inclusion of multiple outlets, a digital load and fuel display, and a two-year warranty are additional advantages. On the downside, some users might find the 8-hour runtime limiting for extended use without refueling. The WEN 3800-Watt Inverter Generator is a well-rounded product with a good balance of power, quiet operation, and user-friendly features, making it ideal for camping, RVing, and other outdoor activities.
